Hired Attorney

While it is unfortunate that I needed to engage counsel for an action against one of the major brokerage and investment banking firms, I am very fortunate to have been introduced to Sean Sweeney of Halling & Cayo. Simply stated, Sean is an outstanding attorney! Sean is smart, professional, methodical and tenacious, which is precisely what I need given the complexities of the case and who opposing counsel is. Additionally, unlike many litigators who come off as being aggressive and combative, Sean is soft spoken, reasonable and tempered. I do not doubt that he can flip the switch when and if he needs to, but his demeanor seems to be that of a deal maker with one eye towards settlement and the other towards trial, as opposed to others who might only want to fight, sometimes at the expense of their clients. I also appreciate how he has explained everything in detail and how he quickly responds to my questions. It is with great pleasure that I can recommend Sean Sweeney
